Is there ever going to be a clever way to import ArchiCAD light sources directly rather than relying on emitting textures ?
Perhaps there is a way to covert what is known about the ArchiCAD light source into an IES texture floating in space the right distance away a from target, and pointing in the right direction?
Messing around trying to achieve spotlight is otherwise insanely slow and not at all intuitive or WYSIWYG in Octane. I prefer Octane light quality, once set up, but for a quick one off render it is far faster just to skip octane and render with built in cinerender, which largely defeats one of the key advantages of having octane.
I think this requires some expert user analysis first.
For example, the Desk Lamp 01 21 - there is physical geometry in the scene, and if you click on on of these lamps, you can see a material "GDL_builtInMatIlluminatio" in the Select from Selection combo box. If you change the material type to Diffuse and add an Emission node, the lamp then works.
But then Ceiling Lamp 21 also has physical geometry, but does NOT have an emitter material, so where is the light supposed to be emitter from?
Area Light 21 has NO physical geometry (ie. ArchiCAD reports no polygons for these objects).
So the conversion rules behind these different lights need to be worked out. I think decoding the way all the General Lights work would be very difficult.
